Proportional Directional Valve 4WRGE16V125L-1X/315G24K31/C1M - Bosch Rexroth R901094822

In roll gap adjustment the spool decides strip thickness. This pilot-operated proportional directional valve in size 16 works at 125 l/min nominal flow with 350 bar operating pressure while reporting spool position internally, so the loop stays calm even as rolling force varies.

Advantages

• 125 l/min nominal flow at 350 bar covers hydraulic roll adjustment on mid-size stands.
• Fully external pilot routing allows a dedicated, finely filtered pilot supply.
• Internal position feedback damps disturbances from the load circuit before they reach the controller.
• ±10 mA command value at the on-board electronics through a 7-pole connector to EN 175201-804.
• Three switching positions across four ports in standard size 16 at 10.03 kg.

Applications

Beyond roll adjustment it serves levellers, loop lifters, strip tension control. The external pilot circuit can carry its own fine filtration, which extends service life in dusty mills.
